First of all I don't know if this technique already exists. I saw the movie "Inception" and saw how they used ear pods while they were asleep to play music at a certain time to know time was running out. I would like to know if if I train myself to recognize a certain sound or music when awake, will I recognize it in a dream and become lucid if I use ear pods while dreaming playing the song/sound during REM sleep?(set an alarm clock six hours into sleep). Or will it make me wake up? or would it not do anything at all?
